Application filed April 21, 1915.

To all whom it may concern Be it known that I, l-lnnnnn'r D. RnMsnN, a citizen of the United States, residing at Port Chester, in the county of 'Westchester and State of New York, have invented certain new and useful Improvements in Machines for Making Nut-l3lanks, of which the following is a full, clear, and exact descripti on, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to nut-making mahines, and with respect to its more specific features, to machines of the character referred to, in which the stock is automatically moved into position to be operated upon by the punches and dies.

One of the objects of the invention is the provision of a simple mechanism for automatically positioning a stock bar accurately with reference to the punches and dies.

Another object of the invention is tl c provision of a practical mechanism which will insure that the stock bar when fed into operative relation with the punches and dies, will be in proper registry with the same. notwithstanding that the stock bar may be more or less warped or irregular in shape.

Another object of the invention is to simplify the stock bar centering mechanism of an automatic nut-making machine.

Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings, forminga part of this specification and wherein similar reference characters refer to similar parts throughout the several views, Figure 1 represents a plan view of so much of the mechanism of an automatic nut blank making machine as may be required'to support the disclosure of the invention; Fig. 2 represents a side view of the stock bar feeding mechanism, the same being partly in section, for a clearer disclosure; Fig. 3 represents a side view of a portion of the mech-.

anism for alining or centering the stock bar; and Fig. 4 represents an end view por tion of the mechanism disclosed in Fig. 3.

This invention more particularly relates to an improvement in the double-acting automatic nut blank machine disclosed in Patent No. 1,088,192 of February 2d, 1914, and has more particularly to do with an improved me-ans for centering the stock bar.

Aside from the differences in construction herein referred to, the construction of the complete machine is to be regarded as similar to that disclosed in the patent above mentioned, to which patent reference may be made for a fuller disclosure of the specific mechanisms and operations. Like the patent, the improved machine involves a main driving gear 1, which may be driven from any suitable source of power and which in turn is adapted to continuously rota-te a main driving shaft 2.

The numeral 3 indicates a reciprocatory punch head carrying a perforating punch 4 and a shearing punch 5, the reciprocation of the head 3 being effected by a sliding block in operative connection with the main driving shaft 2, as explained in the patent.

The numeral 6 represents a die block supporting suitable dies opposite the punches, and as the punches advance toward the dies, the punch 5 will shear oil a perforated nut blank section from the end of a stock bar and the punch l will perforate the bar at a. predetermined preceding part of the bar.

The numeral 7 indicates a rock lever suitably fulcrumed on the machine frame, which lever at one end is suitably connected with a reciprocatorystock bar feeding vise or gripper so that the reciprocations of the lever 7 will feed a stock bar 8 at intervals to the punching mechanism.

The numerals 9 and 10 indicate the gripping jaws of the vise mechanism, which jaws are caused to grip the stock bar 8 through the instrumentality of a rock lever 11. The reciprocatory movements of the rock lovers 7 and 11 are effected through the instrumentality of a member 12, splined to th main driving shaft 2 and having a circumferenti al cam groove 13 to cooperate with the lever 7 and an end or face cam groove 14. for cooperation with the lever 11.

The above construction being similar to that of the patent referred to, it is unnecessary to further specifically describe the same. For convenience it may be noted, however, that upon rotation of the driving shaft 2, the punches 1 and 5 will be reciprocated toward and from the path of the bar to be operated upon, the jaws 9 and 10 will be caused to grip the stock bar, and will thereupon be moved by the lever 7 to advance the stock bar 8 into cooperative relation with the punches. A nut blank section having been sheared from the advanced-end of the bar 8 by the punch 5,'a slight retrograde movement of the bar 8 is effected through the instrumentality of the cam groove 13, after which the punch a perforates the stock bar at a. predetermined point.

The stock bars which are to be sheared and punched by the machine to produce the nut blanks are oftentimes of warped or irregular shape, so that the portion presented to the punching mechanism would not ordinarily be accurately presented thereto if said bars were guided merely in a passageway such as would properly accurately position a perfectly straight bar before the punches and dies. By reason of the some times irregular shape of these bars, the pol tion of the same to be operated upon by the punches may be out of alinement transversely of the plane of operation of the punches, and one of the objects of the present invention is to accurately aline the end angular head 22 for 1 tion of the pivotal of the bar immediately acted upon by the punches and to effect the alinement by mechanism which is simple in construction and efficient in operation.

In the present embodiment, a pair of alining aws 15 and 16 is provided, the faces of the jaws being inclined to each other transversely of the path of feed of the stock bar, said faces being also disposed in planes at angles to opposite sides of the bar. Preferably the bar" alining jaws are stationary relative to each other and are comprised in hardened metallic elements mounted on a carrier 17, which carrier comprises a plate pivotally connected to one end of a rock a m 18, fulcrumed at 19 on the frame of the machine, the other end of the rock arm loosely encircling a stud 20, screw-threaded into the frame, as at 21, and having an the application of a wrench. The stud 20 hasa shoulder 23, against which the adjacent arm of the rock lever 1.8 may rest. By turning the stud 22 it may be adjusted in and out and the posiaxis of the carrier 17 may thusbe changed or adjusted, whereupon the nut 24 may be turned to lock the rock arm, and consequently the pivotal axis, in its adjusted position. The carrier 17 is located to one side of the axis of the perforating punch and is disposed to be moved transversely of the path of feed of the stock bar toward and from said bar. The planes of the alining faces intersect the lines of movement of the jaws around the pivotal axis of the carrier 17, so that when said carrier is moved around its pivoted axis and the jaws caused to contact with the stock bar, the alining faces may initially deflect the bar either upwardly or downwardly, as the case may be, and eventually will alinc the advanced end of the bar with the punches, this end of the bar being moved, or flexed, slightly transversely of the path of movement of the punches. In order that the bar may have an unobstructed entry into the space between the jaws 15 and 16, the faces of said jaws at the side of the carrier adjacent the direction from which the bar approaches are inclined to each other longitudinally of the path of feed, as at 25 and 26, providing a flare for the easy reception of the end of the bar. As before stated, the faces of the jaws are preferably hardened so as to avoid wear as much as possible and at the same time provide rigid jaws which will positively aline this portion of the bar with the punches.

It'is designed to automatically client the alining movement of the alining jaws, and while any suitable operative devices may be employed, it is preferred to utilize for the purpose a part of the machine which has a movement in timed relation with the movement of the stock bar. To this end, the carrier 17 is operatively connected to the reciprocatory punch head 3, so as to cause relative reciprocatory movement tween the bar and jaws transversely of the path of feed of the bar.

The numeral 27 indicates a bracket fastened to the punch head 3, said bracket carrying a pin 28, engaging, and adapted to play in a slot 29 of a reciprocatory member or link 30. Said link also engages a pin 31, disposed at the end of the carrier 1?, said carrier having a fork, COI'IlPllSO/d by the tines 32 and 33, straddling the pin 31.

The numeral 3% indicates a spring connected at one end to a fixed portion of the frame, as at 35, the other end of the spring being provided with a hook-shaped member 36 which takes over the pin 31, passing between tines 37 and 38 of the link 17.

The numeral indicates an abutment, comprised in an adjusting screw carried by the link 30 at one end of the slot, the adjustment of said screw, in effect, adjusting the effective length of the slot 29.

In operation, the vise mechanism advances the bar into the general position to be punched, whereupon the punches advance toward the bar. The advanced movement of the reciprocatory punch head causes the pin 28 to move in the slot 29 toward the end of the carrier 17, thus permitting the carrier 17 to be yieldingly moved toward the stock bar by the spring 84, which spring is under tension sufiicient to effect such movement of the carrier 1'7 and thereby accomplish the alinement of the stool: bar, as explained. The stock bar lnwing been alined by the jaws 15 and 16, the punching operation is effected and thereupon the punch head recedes, and eventually the pin 28 cooperates with the end of the link 30 or the abutment 39, and positively moves the carrier 17 in the opposite direction against the tension of the spring 34-, thereby freeing the bar 8 from the operative effect of the alining jaws. By operating the carrier 17 through the instrumentality of the punch head 3 and by the devices explained, a lost-motion connection between the punches and the alining jaws is provided, and in this wise a positive connection between the alining mechanism and the operative portion of the machine is effected at only that part of the operation of the machine where the movement of the carrier 17 is required, the entire machine thus requiring less power to operate it and a less number of parts than would be required if the carrier 17 were positively moved at all times.

As set forth in the patent above referred to, the present machine is provided with a stop formed by the end of an arm 41 adjustably connected to a hand lever 42 fulcrumcd on the frame of the machine, as at 43, the fulcrum and stop being preferably in alinement with the path of feed of the bar. Disposed below the bar adjacent the punches and adjacent the passageway for the discharge of the scrap left in the bar is a bar supporting member comprising a rock arm 44 having a bar supporting face 45.

he arm 44 is pivotally mounted on an axis 46 and the arm 47 connected to said axis is in turn connected to the hand lever 42 by a link 48. Upon raising the hand lever 42 the stop 40 will be lifted from the path of the bar while the face 5 will be moved away from its bar supporting position. The successive operations of the shearing punch gradually shortens the bar of stock, and eventually the rear end of the bar approaches the punches, being moved by abutting the front end of a succeeding bar against the rear end of the first bar. The face will support the rear end of the foremost bar adjacent the punches so that even a short portion of the rear end of the bar may be properly fed into punching relation with the punches and thereby a shorter piece of scrap left than is ordinarily efiected in machines of this general character. The lowering of the face 45 by manipulation of the hand bar 42, also removes this support from the scrap and permits the latter to gravitate from the path of feed.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the language used in the following claims is intended to cover all of the generic and spe cific features of the invention herein described and all statements of the scope of the invention, which, as a matter of lan guage, might be said to fall therebetween.
